I couldn't figure out how to finish this. I gave it 2 attempts, saw how to move to the zones and hit the button, but had no clue what to do so I didn't die of oxygen deprivation. I looked around the room but couldn't figure out what to interact with. I had to read the comments here to know that it was a thing I could do.
Very atmospheric though and got me hooked at first, but had to give up when I got frustrated.
